IMPROVEMENT IN HORSE-POWERS.

To ALL wHoM 1T 4MAY CONQERN:

Beit known that I, ISAAC KELLER, of Randolph, in the county of Portage, and State of Ohio, have invented new and useful Improvements in Horse-Powers; and I do hereby declare that the following is a full, clear, land exact description of my invention, reference being had to the accompanying drawings, forming-a part of this specication, and-to the letters of reference marked thereon, of which drawingsi Figure 1 is a. plan of my improved horse-power. v

Figure 2 is an elevation of the'same.

Figure 3 is a section made by'plane :v y in iig. 1.

The nature of my invention consists in the placing of all the multiplying-gear of a horse-power in a solid i metallic box, whereby the gear is kept from the dirt-when the power is sitting on the ground, and all the gearwheels which move with considerable velocity are secured in a uniform position withv respect to eaeh other, thus insuring a uniform movement, and preventing any bindingV and undue friction and wear, as must be thecase when the gear is hung in boxes on the separate pieces of the frame, and the frame is sprung or strained out of its exact original form by any outside-action. l v

To enable others"v skilled in the art to make and use my. invention, I'twill proceed to describe its construc- -tion and operation.

The'm'ain frame of my horse-power is composed of the sills C C, which are united by the cross-pieces D D, E E, as shown.

Onthe centre cross-piece D is placed Athe centre-plate T, on which turns the4 hub`S of the muster-wheel A B, which is secured in this position by the centre-boltlt, asshown in tig. 3.

O The master-wheel is composed of therim Aiof Acast metal, of the cross-section' shown in iig. 3, and with gear on the llower face of it, and has the lips a c east on the-inner face, to which the arms Il B, (which cross and are secured to the hub S,) arevsecured. -Y

The holes a are cast in the rim A, and levers are passed thronghthem into the holes b b in'i the hub S, andthe ho1-sesbeinfg attached to the ends of said lever, their power is communicated to the' master-wheel.`

The irons` F F F, ofthe form shown, are arranged on the.'cross-picces D D, and serve to secure a true rotation of themaster-wheel, notwithstanding'irregularities in the plane oi' application of the power.

The multiplying or speeding-gears P J Kai-e hung on axles H I, the wheel `P vmeshing into-the gear on. the lower face' of the rim A oft-hemaster-wheel, andthe wheels J and K meshing into each other. 4

A' universal joint, L, is arranged on the end of the shaft I, to which the shaft M, (which transmits the power to the machine to he driven,) isattached. i i

The bei:` G, which contains the'gear P .I K, is made in general form, as shown, and has at each side the lips d CZ, which supportl the box on Vthe cross-pieces E E, and also servefor the lower part of the bfxes for the journals of the-shafts H and. I; the upper part of these boxes being the covers e'e, which are secured to the lips dd by bolts 7c' k, which pass throughx the covers e e, the lipsd d of the .box G, and 'the cross-piecesA E E, Vand also serve to secure the box G in its proper position on said cross-pieces. f

The iron, N, is made,'in general form,'as shown, and is secured on the cover e by the bolts k lc, and has a lip, n, which projects over the lower ange olthe rim A of the master-wheel, and which prevents -thelnaster-4 wheel from rising np, so .as to throw its teeth out of gear with the wheel P. v

A small hole, g, is made in the lowest portion ofthe box G, which lets oifany water which mightaccumulate in said box, andwhich would burst the box if allowed to remain and freeze. y

It is readily seen that this arrangement keeps the gears P J K free from any dirt which they might scrape up were they not kept from the ground by the b'ox- G, and that they will not be made tolbind by any rocking of the frame C D E, as they are all hung on the axles H and I, which run iii boxesron th'e sides of the solid box G, 'which will not yield to any rocking ofthe frame, and also that the iron, N, with its lip n, insures the gearing of `Vthe master-wheel 'A andthe .first wheel B, as shown.

l Having thus fully described my improved horsepower,` I do not claiunns my invention, any part of the frame C C D D vE E, nor Ithe master-wheel A B B, nor 4the centre-plato T, centre-bolt R, the gear P J K, axles I-I and I, universaljoint L, shaft M, or covers e e; hut

What I do claim as my invention, and desire to secure by Letters Patent, is l. The solid metallic boxvG, Withhole'g therein, when used to contain the speeding-gear PJ K of a. horsepower, substantially in the manner and for the purpose eet forth.

2. The iron, N,with lip u, when used in combination with the box Gr, with its gear I? J K, end the master- I wheel A B B, substantially es and for the purpose herein, specified.

3. peculiar arrangement :mtl combination ef the box G, axles H end I, with gear-wheels P, J, and Ii thereon, iron, N,v with lip fra, and mosterwheel A B, the several ports' being arranged in the manner and for the purpose herein specified. 4

As evidence that I claim the foregoing, I have hereunto set my hand inthe presence of two witnesses, this 26th day of March, A. D. 1868.

ISAAC KELLER.
